Abstract: An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly consists of, a first lens having negative refractive power, a second lens having negative refractive power, and a third lens having positive refractive power. The second lens assembly consists of, a fourth lens having positive refractive power, a fifth lens having positive refractive power, a sixth lens having negative refractive power, and a seventh lens having positive refractive power. An air space is provided between any two adjacent lenses of the seven lenses instead of being adhered to one another. The optical imaging lens satisfies: 0.2<F/fg2<0.5, wherein F is a focal length of the optical imaging lens; fg2 is a focal length of the second lens assembly, thereby achieving the effect of high image quality.
